36.
Explain the difference between conduction and convection.
a)
Conduction involves heat going in all directions while heat rises with convection.
b)
Heat moves in all directions for convection, but it rises for conduction.
c)
Heat rises for convection and travels thru liquids and gases. Conduction travels thru solids and liquids but must be touching.
d)
Thermal energy travels thru solids for both conduction and convection; however, conduction involves direct contact.
37.
Explain the difference between convection and radiation.
a)
Heat travels thru solids and liquids for convection but thru rays, waves, and particles for radiation.
b)
Thermal energy travels thru liquids and gases for convection and rays, waves, and particles for radiation. Heat goes in all directions for radiation and rises for convection.
c)
Convection travels thru liquids and gases and radiation occurs in solids and liquids.
38.
What are the differences and similarities between radiation and conduction?
a)
Both are types of heat transfer. Radiation occurs in all directions thru empty space. Conduction occurs in solids and liquids and must touch.
b)
Conduction occurs in liquids and gases. Radiation occurs in rays, waves, and particles.
